Line A

Do you know the infamous FCC's "Line A" does run through the northern
tier of Ohio?  What does it mean to you and your operations on 420-450 MHz?
Even though Union County is not within Line A, there are other issues and
(such as Commercial Licenses by the FCC in the 420-430 MHz sub-band, and
Canadian Primary status in the 420-430 AND 440-450 MHz sub-bands) that we
must "not cause interference to."  Just a little known, little used set of
rules that could impact your operating in Ohio that we need to keep in
mind.  Scott N8SY started the conversation and article, I emailed him some
specifics that he saw fit to include....
